VAPORIZER.

Application filed May 242,

To aZZ whom it may concern:

Be it known that l, Hnnsnr (I. iinnnn, a citizen of the United States,residing at Norwich, in the county oi Mcllenry and State of NorthDakota,have invented new and useful Improvements in Vaporizers of whichthe following is a specification.

This invention relates to attachments for internal combustion enginesand has for its object the provision of an electrically operated heatingdevice adapted for interposition between the carburetor and the intakemanifold of an internal combustion en whereby to heat the vaporized fuelfor the purpose of increasing the explosive quality or combustibility ofthe mixture.

An important object the provision oi a device of this character which isprovided. with means whereby to admit air into the manifold, a peculiarconstruction being employed for regulating the quantity of air admitted.

.l-ln additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture and installation,highly eilicient in use, durable in service, and a general improvementin the art.

With the above and other objects and advantages in View, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings inwhich Figure 1 is an elevation of my device,

Figure 2 is a plan view, and

Figure- 3 is a longitudinal detail section through the upper portionthereof.

Referring more particularly to the draw ings, l have shown my device ascomprising a body 10 formed of any suitable material and of a size andshape to be interposed be tween a carbureter and the intake manifold ofan engine, the body being provided at its end portions with holes 11 forthe passage of the usual bolts employed in connecting the carburetoroutlet with the intake manifold.

This body is also formed centrally with a circular hole 12 which isrelatively large and through which the mixture from the carbureter maypass. Leading into this hole: 12 is apassage 13 formed in the upperportion of the body and having its upper end flared, as indicated at 14.

The heating means consists of a resistcoil 15 arranged within theopening 12 1921. Serial No. 472,276.

the periphery thereof and connected with terminals of this coil aresuitable binding posts 16 located at one end of the body and adapted iorconnection with current carrying wires leading from any suitable sourcewhich might conveniently be the storage battery of an automobile.

Secured upon th top of the body 10, *hich incidentally is formed withlongitudi- -al guide flanges ll' is an elongated plate provided with aknob 19 and this plate formed centrally with an elongated slot 0registering with the flared entrance openng l-il or the passage 13. Thisplate is also formed near its ends with holes 21 through which passstuds or screws 22 which are threaded into the top of the body. Disposedupon the top of the plate 1.8 is a plate 23 which is formed centrallywith a series 0t holes 24: any one or more of which may be brought intoregistration with the slot 20. This plate 23 is slidable and is providedwith slots guidably engaging the screws 22. One end of this plate 23 isprovided with a knob constituting a handle whereby it may be movedDisposed upon the screws 22 are washers 27 which engage upon the top ofthe plate 23 and surrounding the screws and engaging these washers aresprings 28 which engage against the undersides of the heads or thescrews 22.

In the operation of the device it will be seen that in starting theengine it is preterable, if not actually necessary, to move the plate 23so that the holes 24: therein will. be out of registration with the slot20 so that no air can enter through my device. l l hen starting in coldweather it is advisable to connect current carrying wires to the bindingpost 16 whereupon the resistance coil 15' will become hot from the pasofcurrent therethrough and will effectually heat the mixture passing intothe manifold so that the mixture will be more easily exploded. When theengine is warmed up it is no longer necessary to operate the heatingcoil though such might be continued if found advisable or preferable.When the engine is running strongly it is of advantage to move the plate23 so as to bring one or more of the holes 24: into registration withthe slot 20 so as to permit auxiliary air to pass into the intakemanifold and this will result usually in more even running of the enginewith the expenditure of: less fuel. While it have shown. and described.the

preferred embodiment of my invention, it is of course to be understoodthat I reserve the right to make such changes in the form, constructionand arrangement or parts as will not depart from the spirit of theinvention or the scope ofthe subjoined claims.

Having thus described my invention, I claim:

1. A device of the character described comprising a body adapted forinterposition betweena carburetor and the intake manifold of an internalcombustion engine, said body being provided with a central hole for thepassage of the mixture from the carburetor and being further providedwith a passage leading from said hole to one side of the body, heatingmeans within said hole and a perforated plate slidable upon said side ofthe body for partially covering 01- uncovering the outer end of saidpassage.

2. A device oi the character described comprising a body adapted to beinterposed between a carburetor and the intake manifold of an internalcombustion engine, said body being" provided with a central hole for thepassage of the mixture from the carburetor and being further providedwith a passage leading lrom said hole to one side of the body, heatingmeans within said hole, and a plate movably mounted upon said side ofthe body for partially covering or uncovering said passage.

3.A' device of the character described comprising a body adapted to beinterposed between a carbureter and the intake manifold of an internalcombustion engine, said body being provided with a central hole for thepassage oi the mixture from the carbureter and being further pro *idedwith a passage leading from said hole to the top comprising a bodyadapted to be interposed I between carbureter and the intake manitold ofan internal combustion engine, said body being provided with a centralhole for the passage of the mixture from the carbureter and beingfurther provided with a passage leading from said hole to the top of thebody, means for partially closing said passage comprising a platesecured upon the top of the body and formed with a slot reg isteringwith. said passage, a second plate guidably slidable upon said firstnamed plate and formed with a plurality of holes adapted to be broughtinto registration with said slot, and heating means within the hole insaid body.

In testimony whereof I aflix my signature.
